SNI is a protocol type supported by GOST.

Usage

Server side

gost -L sni://:443

Client side

The SNI proxy service can be used directly by configuring hosts, or use GOST for forwarding:

gost -L :8080 -F sni://server_ip:443

Host obfuscation

In GOST, the SNI client can specify the host alias by using the host parameter:

gost -L :8080 -F sni://server_ip:443?host=example.com

The SNI client replaces the host name in the TLS handshake or HTTP request header with the one specified by the host parameter.

The SNI protocol can be used in combination with various transport types

SNI Over TLS

gost -L sni+tls://:443

SNI Over Websocket

gost -L sni+ws://:443
